HERBERT ABRAHAM, OF BOUNDBROOK, NEW JERSEY.

PROCESS AND APPARATUS FOR THE MANUFACTURE AND PREPARATION OF ROOFING- STRIPS.

Application filed October 21, 1908.

To all whom it may concern:

Be it known that I, HERBERT ABRAHAM, a citizen of the United States, and a resident of Boundbrook, county of Somerset, and State of New Jersey, have invented certain new and useful Improvements in the Process and Ap aratus for the Manufacture and Preparat'on of Roofing-Strips, of which the following is a specification.

My invention relates to the manufacture and preparation of roofing strips and especially comprehends a novel manner of producing improved serrated roofing strips, with a peculiar arrangement of apparatus therefor.

Various and important objects of my invention are, not only to produce serrated roofing strips which have been treated or saturated with a protective compound, but also to produce serrated roofing strips in which the serrated edges as well as the flat surfaces of the strips shall have a plied to them a protective or weatherproo coating.

In general it is the object of my invention to provide an arrangement which is conducive to economy and efficiency of operation and construction, and to increase the durability and efliciency of such serrated roofing strips.

Further objects, advantages and features will more clearly appear from the detail description given below, taken in connection with the accompanyin drawing which forms a part of this speci cation.

In the drawing, Figure 1 is a perspective view showing various )arts of one form of a novel apparatus an rocess which produce my improved roo ng strips. Fig. 2 shows a section through the saturating tank. Fig. 3 is a section through one of the coating tanks showing the coating rolls. Fig. 4 is a plan view of a portion of one of my improved roofing strips, and Fig. 5 is a section thereof taken on the line V-VL Referring to Figs. 1 and 2, 1 represents an elongated sheet of roofing material, such as felt, paper, burlap, or other suitable material, but preferably of felt. The sheet 1 is guided through thesaturating or impregnating tank '2 by means of guiding rollers 3.

Specification of Letters Patent.

Patented Feb. 2, 1915.

Serial No. 458,807.

In the tank 2 is a compound 4 rendered fluid by means of heat which is designed to saturate or impregnate the sheet 1 and to protect it from elemental and other deterioratlug actions. Within the tank 2 are steam pipes 20 which properly heat the compound 4 so that it is easily and readily absorbed by the sheet 1. For the sake of clearness the impregnating material 4, steam pipes 20 are omitted in Pig. 1. These are, however, clearly shown in Fig. 2. The saturating or impregnating compound 4 preferably consists of a soft non-hardening compound con taining resins, oils, fats, waxes, bitumens, tars, pitches or their equivalents, either singly or in combination. It is not to be understood, however, that this is the onl form of saturation that may be employed, or any compound which will render the fabric waterproof and pliable may likewise be used to advantage.

After leaving the tank 2 and guiding rolls 3 the sheet 1 is carried to cutting rolls 5 one of which possesses a zigzag cutter 6. The cutter 6 is arranged to cut a zigzag or other path through the sheet 1, splitting it longitudinally into two roofing strips and 8, each with serrations or notches 9. r rom the cutting rolls the strip 7 is carried upward to the coating or facing rolls 10 which operate to apply a coating or facing material from the pan 11 to the strip. At the same time the strip 8 is carried downward to similar coating or facing rolls 12 and pan 13. The coating rolls 10 and 12 take up on their surfaces the melted coating compound or facing material 14 from the pans 11 and 13 and apply it to the strips 7 and 8 (see also Fi 3). The pans 11 and 13 are provided wit steam pipes 19 to heat the compound 14 so that it will be fluid enough to be properly applied to the strips. For the sake of clearness the compound 14 and the steam pipes 19 are omitted from Fig. l. but are clearly shown in Fig. 3.

Adjacent to the coating or facing rolls are troughs 16 which feed the hot facing compound 14 to the tops of the strips 7 and 8. The hot compound 14 is fed to the trou hs 16 by supply tubes 17 from any suita le source. The compound 14 is deposited by the troughs 16 in the center of the strips 7 and H and beneath the up er rolls 10 and 12. This is clearly shown in Fig. 3. The upper rolls 10 and 12 spread the coating or facing over the upper surface of the strips and incidentally both edges of the strips 7 and B and especially the serrated edges 9 of said strips ave the proper amount of this coating applied to them. The facin material or compound 14 is preferably 0 a harder consistency than that used in the tank 2 for impregnating, and it may consist of one or more of the ingredients mentioned in connection with the latter, viz, materials of a resinous, fatty, waxv, bituminous, tarr or pitchy nature; or it may be composed o the particular ingredients set forth in United States Patent No. 775,635 or 77 5,636.

After leaving the coating rolls 10 and 12 the strips are coiled into rolls or otherwise conveniently put up in marketable shape. If desired the roofing strips ma be surfaced with powdered soapstone or 0 er material to prevent them from sticking together when rolled or otherwise acked.

Referring to Figs. 4 an 5, 1 show a portion of the serrated roofi strip 8 with the serrations or notches 9 ereon. In these figures various of the dimensions have been greatl exaggerated in order to clearly show that e coating 15 from the coating rolls 12 is applied to the edges as well as to one of the flat surfaces of t e strip.

By the above method and means, in which the firm, pliable, water roof and weatherproof coating 14 is app 'ed after the sheet 1 is cut into the strips ,7 and 8, serrated roofing strips are produced in which the edges, and especially the serrated edges, are fully protected from the detrimental action of the weather and other causes. The coating or facing 15 not only protects the edges of the stri s from the detrimental action of water an the climate but also reinforces the edges and prevents them from cracking, swelling, etc. This is especially important since it is usually the serrated ed es which lie exposed and are more liable to eteriorate or become damaged. By my improvements I also produce two serrated strips with only one cutter and the whole arrangement is conducive to economy and efiiciency of operation and construction.

Although I have described my improvements in great detail, I do not limit myself to such details, but,

Having full and clearly set forth my invention what claim as new and desire to secure by Letters Patent, is:

- 1. The improved process for producing flexible waterproof roofing stri s which consists in impregnating a web 0 suitable material with a protective weatherproofing compound, cutting the impregnated web into strips and then coating the strips with a protective weatherproofin substance so that the coating will be app ied to the cut edges thereof.

2. The im roved'process for producing serrated rooiiii pregnating a web 0 sheet material with a protective compound, cutting the impregnated web into serrated strips and then facing the strips with a protective weatherproofing substance so that the facing will be applied to the cut edges thereof.

3. The improved process for serrated flexible waterproof roo g strips which consists in impregnatin a web of sheet material with an aspha tic composition, cutting said impregnated web into serrated strips and then coating said strips with a coating of asphaltic or bituminous material so that the coating will be applied to the cut edges of the strips.

4. The improved process for reducing serrated flexible waterproof roo g strips which consists in impregnating a web of suitable material with a waterproofing compound, cutting said web into impregnated strips and then facing said strips with a waterproofing compound so that the facing will be applied to t e cut edges of thestrips.

5. The lmproved process for reducing serrated flexible waterproof rooliiig strips which consists in cutting a web of suitable material into strips with serrated edges and then simultaneously facing said strips with a protective weatherproofin coating so that the coating will be applie to the cut ser: rated edges of said strips.

6. In a machine of the class described, the

roducing combination of means for cutting a zigzag path through a sheet of suitable materia to form serrated strips, means for applying a protective weatherproofing coating to the lower faces of said strips and means for applying a protective coating to the upper faces of said strips said means being arranged to also apply said coating to the edges of said strips.

7. The improved process of producing flexible weatherproof roofing which consists in impregnating a strip of suitable material with a protective weather-proofing compound, cutting an edge of the impregnated weatherproof strip so as to form serrations or notches along the edge and then coating the cut edges of the serrations or notches with a protective weatherproofing substance.

8. The improved process of producing flexible weatherproof roofing which consists in impregnating a strip of suitable material with a protective weatherproofing compound, cutting an edge of the weatherproof .7 0 g stri s which conslsts in imstrip so as to form serrations or notches along the edge and then coating the cut edges of the serrations or notches with a rotective weather-proofing substance of a arder consistency than that of the impregnating compound.

In testimony whereof, I have signed my name to this s ification, in the presence of two subscriblng witnesses.
